- stack portions are tied together so as to be transportable in units bya mechanical` lifter.

3. ln akiln having bricks formed to provide parallel fuel arches, a.unit of bricks corresponding in width to the distance between arches,arranged in separated relation for kiln burning, the bottom portionthereof having the bricks massed in pairs two high to leave straight,parallel openings between pairs entirely across the bottom of the stackto promote circulation and adapted to-receive the ngers of a mechanicallifter to transport said unit bodily to position.

4t. A unit of bricks in separated relation for kiln burning, the twobottom courses extending in the same direction and massed together inpairs two high to leave enlarged openingsbetween pairs to promotecirculation and receive the fingers of a mechanical lifter, and thelayers next above said bottom courses extending alternately lengthwiseand crosswise of the unit whereby it is tied together and may be bodilytransported by such mechanical lifter.

A plurality of brick stacks arranged. side 'by side for=kiln burning,the bottom portions of the stacks having the bricks hunched in pairs twohigh to provide cnlarged openings, whereby connection for continuousheat circulation betweengthe several stacks is provided and spacesprovided to receive the lingers of a mechanical. lifter 'so that thestacks may be bodily transported in units.

6. The method of forming a brickarch for kiln burning which consists indepositing rectangular units of bricks in separated relation and inre-arranging with the bricks in alternate layers extending at rightangles to each. other and drawing out the top portion to form an arch.

7. The herein described method of buildingr an arch-burning kiln,consisting of piling a stack of bricks in a rectangular unit, the bodythereof having the bricks in separated rcl ation suitable for burningpurposes, and the lower bricks being spaced transversely of the unit toconstitute heat transmission passages, turning certain ot' the topcourses to extend trans\f'ersely of the unit,

and` pulling said top courses outwardly int-o 'an overhanging positionto constitute a portion of the top of an arch of the kiln.

8. The herein described method of building an arch-burning kiln,consisting of piling a stackv of bricks in a rectangular unit, the bodythereof having the bricks in separated relation suitable for burningpurposes, and the lower bricks being spaced transversely ot the unit toconstitute heat transmission passages, turning certain of the topcourses to extend transversely of the unit, and pulling outward theturned bricks and the course above said turned bricks into anoverhanging position, with'the uppermost course 'of outwardly pulledbricks extending beyond the outwardly pulled turned bricks, toconstitute a portion of the top of the arch.

9. The herein described method of buildl ing an arch-burning kiln,consisting of piling a stack of bricks in a rectangular unit,

the body' thereof having the bricks in sepa-- rated relation suitablefor burning purposes, and the lower bricks bein spaced transversely ofthe unit to constitute heat transmission passages, turning certain ofthe top courses to extend transversely of the unit, and pulling outwardthe turned bricks and the course above said turned bricks into anoverhanging position, with the uppermost course of outwardly pulledbricks extending beyond the outwardly pulled turned bricks,

then filling in with extra bricks the intermediate spaces in the top ofthe unit which are'fornied by the pulling out of bricks of said topcourses.

10. rlhe hereindescribed method of build'- ing an arch-burning kiln,consisting o-piling a stack of bricks in a rectangular unit, the bodythereof having the bricks in separated relation suitable for burningpurposes, and the lower bricks being spaced transversely of the unittorconstitute heat transmission passages, transporting to final positionin the kiln the unit in aforesaid stacked relation, turning certain ofthe top courses' to extend transversely of the unit, and pulling saidtop courses outwardly into an overhanging position to constitute aportion of the top of an arch of the kiln.

11. The herein described method of building an arch-burning kiln,consisting of stacki'ngthe bricks in rectangular units in burningformation, transporting'- said rectangular units into proper position toconstitute the pillars or brick bodies between adjacent arches, turningthe outer bricks of certain of the top courses on adjacent sides -toconstitute a portion of the top of the arch,

ice

of said two adjacent units to extend trans- Walls of which are formed byhe adjacent sides of said two adjacent units.

12. The herein described method of building an rarch-burning kiln,consisting of .stacking the bricks in rectangular units in burningformation, transporting said rec tangular units into proper position toconstitute the pillars or brick bodiesbetween adjacent arches, providingtransverse bottom passages from arch to arch for free heat circulation,turning the outer brie-ks of certain of the top courses on adjacentsides of said two adjacent units to extend transversely of the unit, andpulling these turned bricks and other adjacent course bricks of saidadjacent units toward each other to form thereby the top of an arch, theupright walls of which are formed by the adjacent sides of said twoadjacent units.

In testimony whereof, I have signed my name to this specification, inthe presence of two subscribing witnesses.
